DETAILED DESCRIPTION

A method and system for bone fixation is disclosed herein. Morespecifically, a method and system for corrective surgery by bonecompression is disclosed. The present disclosure provides disclosure ofa plate that facilitates the compression of bone segments or bonepieces. The concepts described herein in relation to bone plates mayalso be applicable to other body parts such as joints. The presentdisclosure describes bone plates comprising at least two components thatmate with each other to form a corrective construct from two bonesegments.

Provided herein is a device and method for carrying out correctivesurgery and bone fixation. In the various embodiments described hereinand corresponding with the Figures provided herewith, a bone plate isdisclosed. The bone plate may be a compression bone plate which isdynamic and facilitates fine adjustments to provide precision duringbone correction procedures. In an embodiment, the bone plate comprises afirst bone plate component and a second bone plate component. The firstbone plate component may comprise at least one hole configured forreceiving bone screws for attachment to a first bone segment, and a malecomponent. The second bone plate component may comprise at least onehole configured for receiving bone screws for attachment to a secondbone segment, and a female component configured for mating with the malecomponent of the first bone plate component. The male component isadjustable after mating with the female component to adjust a positionof the first bone plate component with respect to the second bone platecomponent.

FIG. 1 illustrates an exemplary bone plate in a dovetail implementation,in accordance with an embodiment. FIG. 1 illustrates a dovetailimplementation of a bone plate in accordance with an embodiment of thepresent disclosure. Bone plate 100, as shown, includes a first boneplate component 110 and a second bone plate component 120. First boneplate component 110 includes holes 111 and 112 for receiving bone screws131 and 132, respectively. Bone screws 131 and 132 are screwed into afirst bone segment (not shown) through holes 111 and 112, respectively,to attach first bone plate component 110 to the first bone segment.First bone plate component 110 also includes a male component 113 ordovetail, which is used for attaching first bone plate component 110 tosecond bone plate component 120 to facilitate compression of each offirst bone plate component 110 and second bone plate component 120,which causes compression between the first bone segment and a secondbone segment attached to second bone plate component 120. Thecompression results in the creation of a corrective bone construct.Second bone plate component 120 also includes holes, such as holes 121and 122, for receiving screws 133 and 134, respectively. Bone screws 133and 134 are screwed into a second bone segment (not shown) through holes121 and 122, respectively, to attach second bone plate component 120 tothe second bone segment. Second bone plate component 120 also includes afemale component 123, which may comprise a receptacle for receiving malecomponent 113. Male component 113 and female component 123 are slidablycoupled and fit together telescopically.

After male component 113 has been inserted into or mated with femalecomponent 123, the position of male component 113 within femalecomponent 123 is adjustable, which results in an adjustment of theposition of first bone plate component 110 with respect to second boneplate component 120. As each of first bone plate component 110 andsecond bone plate component 120 are attached to a corresponding bonesegment, the position of the bone segments are also thus adjustable.Adjustment may result in compression of the bone segments, causing thebone segments to move closer to each other to form a correctiveconstruct.

After adjustment of male component 113 within female component 123 iscomplete, the first bone plate component 110 and the second bone platecomponent 120 must be locked into place. Locking may be facilitated bynumerous means. In an embodiment, a bone screw, such as those shown, maybe tightened, resulting in the head of the bone screw impinging on themale component 113, which results in locking the male component 113 inplace. In another embodiment, a secondary locking screw, when tightened,may lock male component 113 in place by interference. Thus, when thescrew is not fully seated or fully screwed into a screw hole, malecomponent 113 may move freely, and thus be adjustable, until the screwis fully tightened.

For example, hole 124, may be used as a dedicated hole for receiving abone screw or locking screw which locks male component 113 in placebased on at least the locking methods described above. Alternatively,male component 113 may be notched and the screw inserted into hole 124may be inserted into and secured with the notch of male component 113.

While the embodiments described herein each embody differentcharacteristics, it is understood to one of ordinary skill in the artthat features of all embodiments described herein with respect to eachof the individual Figures may be combined with features described withrespect to other Figures of the present disclosure.

FIG. 2 illustrates a view of a bone screw, in accordance with anembodiment. FIG. 2 illustrates a conventional bone screw that may beused to affix bone plates to bone segments or body segments, inaccordance with the embodiments described herein.

FIG. 3 illustrates a cross section view of how a bone screw contacts anangular surface of a bone plate, in accordance with an embodiment. FIG.3 illustrates how a top portion of a bone screw may lock a malecomponent into place within a female component. For example, bone screw302 as shown, includes a bone screw top 304. Bone screw 302 has beeninserted through hole 306 of a second plate component 308. Second platecomponent 308 includes a female component 310 which may be a receptaclefor receiving a male component 312. Bone screw top 304, as shown,contacts an angular surface of male component 312. As bone screw 302 isscrewed tighter within hole 306, bone screw top 304 increases contactand impinges the angular surface of male component 312 which is nestledwithin female component 310. This locks male component 312 into placewithin female component 310 and thus locks a first plate component andsecond plate component in position with respect to each other and as aresult, locks the position of a first and second bone segment to form acorrective construct.

FIG. 4A illustrates a perspective view of a component of a bone plate,in accordance with an embodiment. FIG. 4A shows a perspective view ofsecond bone plate component 120, including female component 123, andholes 121, 122, and 124. The perspective view shows how each of theholes 121, 122, and 124 facilitate locking of a male component insertedinto female component 123 when a bone screw is inserted and tightenedinto each of the holes.

4B illustrates another perspective view of a component of a bone plate,in accordance with an embodiment. FIG. 4B shows a different perspectiveof the second bone plate component 120 as also shown by 4A.

FIG. 5 illustrates a perspective view of a component of a bone plate, inaccordance with an embodiment. FIG. 5 shows a perspective view of firstbone plate component 110. Holes 111 and 112 are shown for receiving bonescrews. Male component 113 is also shown, wherein male component 113 isconfigured for mating with female component of second bone platecomponent 120 as shown by FIG. 4A and 4B, as well as FIG. 1.

FIG. 6 illustrates an exemplary bone plate in an alternate dovetailimplementation, in accordance with an embodiment. Bone plate 600, asshown, includes a first bone plate component 610 and a second bone platecomponent 620. First bone plate component 610 may include a basecomponent 640 which includes holes 611 and 612 for receiving bone screws631 and 632, respectively. Bone screws 631 and 632 are screwed into afirst bone segment (not shown) through holes 611 and 612, respectively,to attach first bone plate component 610 to the first bone segment.First bone plate component 610 also includes a male component 613 whichis used for attaching first bone plate component 610 to second boneplate component 620 to facilitate compression of each of first boneplate component 610 and second bone plate component 620, which causescompression between the first bone segment and a second bone segmentattached to second bone plate component 620. Male component 613 mayinclude a hole 641 for receiving bone screw 632 that goes through bothhole 641 and hole 612 to hold and/or lock male component 613 to basecomponent 640 of first bone plate component 610. Base component 640further includes a bearing surface 643 which facilitates multiplanarmovement of male component 613, allowing for angular adjustments to bemade to male component 613. The compression results in the creation of acorrective bone construct. A spherical bearing surface as shown mayfacilitate reduction of complex fractures or closure of segments asopposed to those without geometric surfaces or pathways.

In an embodiment, male component 613 is placed into the bearing surface643 of base component 640. Once a multiplanar angle of male component613 has been selected, a bone screw 632 may be inserted through bothhole 612 and hole 641. Once bone screw 632 is tightened or fastened,male component 613 is locked into place in bearing surface 643 withrespect to base component 640.

Second bone plate component 620 also includes holes, such as holes 621and 622, for receiving screws 633 and 634, respectively. Bone screws 633and 634 are screwed into a second bone segment (not shown) through holes621 and 622, respectively, to attach second bone plate component 620 tothe second bone segment. Second bone plate component 620 also includesat least one female component 623, which may comprise a receptacle forreceiving a male component such as male component 613.

Either or both male component 613 or any of female components 623 mayinclude serrations or grooves to increase resistance, thus providing amore secure locking mechanism and also allowing for more preciseadjustments. For example, male component 613 includes teeth orserrations 650 cut along a portion of its bottom surface. This allowsmale component 613 to function as a gear rack. Thus, an external piniongear (not shown) may engage the teeth or serrations to provide bonecompression, distraction, or both. Turning or usage of the pinion gearwill cause adjustment of a position of the male component 613 in eitherof two directions laterally with respect to female component 623. Thisin turn results in adjustments of position between first bone platecomponent 610 and second bone plate component 620.

Second bone plate component 620 as shown includes two female components623. Usage of multiple female components facilitates connection withmultiple male components to further provide stability in joining bone orbody segments using bone plate 600.

In an embodiment, male component 613 is locked into place within femalecomponent 623 based on a tightening of bone screws 633 and 634. As shownin FIG. 6, bone screws 633 and 634, when tightened, press against malecomponent 613, thereby preventing male component 613 from moving withinfemale component 623.

FIG. 7 illustrates an exemplary bone plate in an alternate dovetailimplementation, in accordance with an embodiment. FIG. 7 illustratesbone plate 600 as also shown by FIG. 6. Bone plate 600 as shownadditionally includes a second male component 613 mated with femalecomponent 623. The addition of another male component provides furtherstability for forming a corrective construct and also facilitates theaddition of another base component 640 in conjunction with the secondmale component 613.

FIG. 8 illustrates an exemplary plate component, in accordance with anembodiment. FIG. 8 provides a close up view of base component 640 offirst bone plate component 610. As shown, base component 640 includesholes 611 and 612. These holes facilitate insertion of bone screws toattach base component 640 to a first bone segment. Also shown isspherical bearing surface 643, which may be concave, and facilitates aball joint type motion to occur when a male component is placed therein.Once a male component is placed within spherical bearing surface 643, abone screw, or a screw with machine threads may be used to lock down themale component within bearing surface 643. As bearing surface 643 isconcave and allows multiplanar motion, prior to locking down the malecomponent, the male component may be adjusted at a desired angle.

FIG. 12 illustrates an exemplary bone plate including a discrete lockingscrew construct, in accordance with an embodiment. Bone plate 1200 asshown by FIG. 12 facilitates locking of a male component 1213 to a basecomponent 1240 of a first bone plate component 1210 by using a discretelocking screw construct comprising a machine threaded dedicated screw1241 that may be inserted through hole 1241 of male component 1213 andthrough hole 1215 of base component 1240.

Bone plate 1200, as shown, includes a first bone plate component 1210and a second bone plate component 1220. First bone plate component 1210may include a base component 1240 which includes holes 1211 and 1212 forreceiving bone screws 1231 and 1232, respectively. Base component 1240also includes hole 1215 for receiving screw 1260 as discussed above.Bone screws 1231 and 1232 are screwed into a first bone segment (notshown) through holes 1211 and 1212, respectively, to attach first boneplate component 1210 to the first bone segment. Screw 1260 is used tofasten male component 1613 to base component 1640.

First bone plate component 1210 also includes a male component 1213which is used for attaching first bone plate component 1210 to secondbone plate component 1220 to facilitate compression of each of firstbone plate component 1210 and second bone plate component 1220, whichcauses compression between the first bone segment and a second bonesegment attached to second bone plate component 1220. Male component1213, as discussed above, may include a hole 1241 for receiving screw1260 which may comprise machine threads. that goes through both hole1241 and hole 1215 to hold and/or lock male component 1213 to basecomponent 1240 of first bone plate component 1210. Base component 1240further includes a bearing surface 1243 which facilitates multiplanarmovement of male component 1213, allowing for angular adjustments to bemade to male component 1213. The compression results in the creation ofa corrective bone construct. A spherical bearing surface facilitatesreduction of complex fractures or closure of segments without geometricsurfaces or pathways.

In an embodiment, male component 1213 is placed into the bearing surface1243 of base component 1240. Once a multiplanar angle of male component1213 has been selected, a screw 1260 may be inserted through both hole1215 and hole 1241. Once screw 1260 is tightened or fastened, malecomponent 1213 is locked into place in bearing surface 1243 with respectto base component 1240.

Second bone plate component 1220 also includes holes, such as holes 1221and 1222, for receiving screws 1233 and 1234, respectively. Bone screws1233 and 1234 are screwed into a second bone segment (not shown) throughholes 1221 and 1222, respectively, to attach second bone plate component1220 to the second bone segment. Second bone plate component 1220 alsoincludes a female component 1223, which may comprise a receptacle forreceiving a male component such as male component 1213.

Either or both male component 1213 and female components 1223 mayinclude serrations or grooves to increase resistance, thus providing amore secure locking mechanism and also allowing for more preciseadjustments. For example, male component 1213 includes teeth orserrations 1250 cut along a portion of its bottom surface. This allowsmale component 1213 to function as a gear rack. Thus, an external piniongear (not shown) may engage the teeth or serrations to provide bonecompression, distraction, or both. Turning or usage of the pinion gearwill cause adjustment of a position of the male component 1213 in eitherof two directions laterally with respect to female component 1223. Thisin turn results in adjustments of position between first bone platecomponent 1210 and second bone plate component 1220. alternatively, theteeth may be in the side of the male component 1213.

In an embodiment, male component 1213 is locked into place within femalecomponent 1223 based on a tightening of bone screws 1233 and 1234.
